Black Perpendicular Lines Appear?

Hi, I am new to the forum so here is my first question:
While modeling a really bad face, 3 lines appeared in a perpendicular shape. I have no idea how I formed them but I really want to get rid of them. They contain no lines, faces, edges, nor vertexes so I can’t delete them! This is probably a really basic problem but I have no idea how to remove them. I have attached a photo for guidance as to what they look like. Please show me how to remove them and what they are! Thanks in advanced!



Thanks again!
